There is a R6RS distribution located at gambit-r6rs.tgz. There is a compile script written in Gambit scheme that will compile all the libraries together into a loadable library. The libraries are divided into 3 layers; each layer being dependent on the previous layer.

1. The Gambit libraries are where all the extensions to r5rs are put
2. the standard and base libraries.
3. The srfi's that are implemented by gambit.
